Radon testing FAQ
Common questions about radon and the testing process.
How do I know if my home has radon? A: You can't see, smell, or taste radon — the only way to know is to test. Testing is simple, non-invasive, and gives you a definitive answer.
What radon level is considered unsafe? A: The EPA recommends taking action if indoor radon levels reach 4 pCi/L or higher. Levels between 2–4 pCi/L are considered elevated and worth addressing.
How long does radon testing take? A: Monitors are placed on-site for 48 hours. After we retrieve the equipment, your written report is delivered within approximately 24 hours — total turnaround is about 3 business days.
Do I need to be home during testing? A: You need to be available for monitor placement and retrieval. During the 48-hour monitoring period, you can go about your normal routine.
Is radon common in the Chicagoland area? A: Yes. Illinois — including DuPage County and the greater Chicagoland area — has elevated radon potential due to local soil and geology. Testing is especially recommended for lower-level living spaces and basements.
What happens if my radon levels are high? A: Your report will explain your results clearly. If levels require action, we can point you toward licensed radon mitigation professionals — we focus on testing so you get an independent, unbiased result.
